From the parking area, walk south on Route 9W for a few hundred feet. Just beyond road signs for Routes 9W and 202, you'll see three blue blazes and three red-dot-on-white blazes on a tree adjacent to the road. These blazes mark the start of the Timp-Torne (blue) and Ramapo-Dunderberg (red-dot-on-white) trails. You'll be following the Timp-Torne...

I went up the RD this morning,as it is more exposed to the sun, and came back on the TT, which had more shade and less ups and downs.  I also extended the hike to the Timp, making a 10 mile loop.

Wow was it hot today, but this hike was worth it! The path just challenging enough and the views were spectacular.

Good trail. One of the longer hikes that I have done - GPS logged it as 8.0 miles and I did it in 5hrs. & 20 mins.
